What is the classification of plastic foil?
4. A long boot time, if the bubble gum tank ones, may cause local lack of plastic cot available Our special defoamers defoaming or spray mix was added after use.
5. Wet weather, the humidity is too large, the glue curing speed partial slow, machine speed can be appropriately reduced or bake an appropriate increase in temperature regulation.
3. Cots glue on both ends of the remaining glue after long squeegeeing, after curing adhesive into the groove, bring rubber roller, it may lead to composite paperboard irregular size of the fine particles. To prevent this phenomenon, the glue should be circulating in the circulating pump suction pump head with 200 mesh nylon cloth tied around so that after filtration using glue.
Operation using plastic foil process:
1, a composite washing machine, put glue into the glue storage tank or directly into the recycling plastic tank. Bake the temperature is 70--95 ℃, speed of 30-50m / min. Or so.2. The amount of glue 5-10 grams per square meter, the air humidity is 25 degrees 60%, the paper humidity 16-20%; Shandong Huacheng Hi-Tech Co., Ltd. aluminum foil adhesive glue glue 25Y 6 grams per square Meter.
2. The main component of polyvinyl acetate emulsion adhesive foil.
3. The main component is aluminum foil of polyvinyl alcohol gel.
Major categories of aluminum foil and plastic main components:
Generally divided into three types:
1. The main components of the aqueous emulsion polymerization of acrylic plastic foil.
